adding child properties to the parent node via java code

[Shivanandh]

i need to add email address from all child nodes that are having, to the parent node but I'm unable to replicate my changes . my changes are not reflcting in the aem node . this is the code I'm using . ive installed the folder node from the package manager.

@Shivanandh Does this service user has write access to that repo path? Did you see any error in the logs?

[Shivanandh]

I can not see any logs in error.log in log support . i can see my component service in active but it is not relfecting anything . how can i debug this . or where can i see logs for this . please help me 

you can igonre the service user name changing. i have created new one as in the ss

[Hemant_arora]

Please see  if your service user is created, and mapping is registered

paramMap.put(ResourceResolverFactory.SUBSERVICE, serviceUser);.

Share logs.

Additionally use ModifiableValumap instead of node api

[Shivanandh]

hii @Hemant_arora    the service user is created and logs i can not see any logs in error.log related to this file . but the service is registering . can you help me how to resolve the replication . 

the above code i have given diff service user . but i created new user and giving you ss. and i have also aletered the code to this user

As everyone has already pointed out, you must check the logs to find what is the issue with your code, the code should do the work (although you could clean up a little bit), but most likely there is an issue either with the User not being able to login or with the User not having permissions to write in the "some" node you are attempting to write. The only way to understand what's going on is either checking the logs or debugging locally.

Please read these articles which explain in detail how to do both things:

After you successfully check the logs or debug I am sure you will be able to resolve the issue, otherwise post back what you find in the logs
